SPECIFICATION forming part of Letters Patent N o. 487,785, datedDecember 13, 1892.

Application tiled July *29, 1892. Serial No. 441.633. (No model.)

To all whom t may concern:

Be it known that I, CHARLES SEYMOUR, a resident of Defiance, in thecounty of Defiance and State of Ohio, have invented certain newV anduseful Improvements in Polishing-Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in machines for polishing objectsof wood or other material, the object of the invention being to producea machine for the purpose stated which shall be of compact constructionand neat in appearance.

A further object is to produce simple and efficient means for supportinga polishingbelt and securing the proper tension thereof.

With these objects in view the invention consists of certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of my improvedmachine. Fig. 2 is an end view. Fig. 3 is a horizontal sectional View.

A represents a combined hollow base and support, the upper portion ofwhich is preferably contracted somewhat and made to projecthorizontally. Secured to one side of the hollow support in any suitablemanner is a yoke B, having boxes a for the accommodation of a shaft b,which latter carries a hollow pulley B between the arms of the yoke B.One end of the shaft b is extended beyond its bearing for the receptionof tight and loose pulleys c c for the accommodation of a belt from anyconvenient source of power.

Secured to the hollow standard at the side thereof opposite to the yokeB is a sleeve C, through which a tube or cylinder C is adapted to passfreely, one end of said tube or cylinder being closed, as at d, and theportion d provided with a screw-threaded perforation for theaccommodation of a screw D. A yoke E is secured to the outer end of thetube or cylinder C and provided with boxes e for the accommodation of ashaft e', which carries a hollow pulley B2. One end of the screw Dpasses into the tube or cylinder C', While the other end has its bearingin a block or bracket f, secured to the yoke B. A beveltoothed wheel gissecured to the screw D and meshes with a bevel-pinion h, carried by ashaft t'. The shaft i is supported in a sleeve j, which passes throughthe wall of the hollow standard, said sleeve having a iiange j', wherebyto secure it to the standard. A hand-wheel la is secured to the outer orfree end of the shaft t', by means of which to turn it. A band or beltE', having a roughened or polishing surface of sand, emery, or othersuitable material, is passed about the pulleys B B2. The objects to bepolished will be brought into contact with this band or belt. By thusconstructing and arranging the machine the tension of the band or belt Emay be easily and quickly adjusted by simply turning the hand-wheel 7s.

The machine is very simple in construction, easy to manipulate, neat inappearance, and effectual in the performance of its functions.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is ,Y

1. In a polishing-machine, the combination, with a post or upright, of ayoke secured thereto, a pulley carried by said yoke, a sleeve secured tothe other side of said post or standard, a tube or cylinder adapted topass loosely through said sleeve, a yoke secured to the sleeve, a pulleycarried by the yoke, a screw passing through one end of the tube orcylinder, a toothed wheel carried by said screw, a shaft passing throughthe wall of the post or standard, a pinion carried by said shaft andmeshing with the toothed wheel, and a handwheel carried by said shaft,and a polishing band or belt passing over said pulleys, substantially asset forth.

2. In a polishing-machine, the combination, with a hollow post orupright, of Ia yoke secured thereto, a pulley carried by said yoke, 9 5

a sleeve secured to the other side of the post or upright, a cylinder ortube passing loosely through said sleeve and into the hollow post orupright, a screw passing through one end of said cylinder or tube, abracket secured to IOO said yoke and serving as a bearing for one end ofthe screw, a. toothed wheel carried by the Screw, a sleeve passingthrough the Wall of the hollow post or upright, a shaft passing throughsaid sleeve, :L pinion carried by said shaft and adapted to mesh withthe toothed Wheel on the screw, a hand-wheel Carried by said shaft, a,yoke secured to the cylinder or tube, a pulley carried by said yoke, anda polishing band or belt passing over` said pul- 1o leys, substantiallyas set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

CHARLES SEYMOUR.
